"When you sweep the garden, you are sweeping your mind."
A daily chore, sweeping the garden, as feeding my feathered friends leaves a big mess of left-over seeds and husks. But the Sansevieria (Mother-in-Law's Tongue) doesn't seem to mind all the husks and the Callisia repens is absolutely flourishing! And all the left-over seeds that blow into the garden germinate and come up all over, providing extra sustenance for the birds as they absolutely love all the fresh greenery! So unless you don't mind some "untidy" looking beds, better to feed your birds further away from your prized beds.
